 Eclogite,   one   of   the   important   lithologies   in   the   main   hole   of   the   Chinese   Continental Scientific Drilling (CCSD) Project, exists above the depth of 3 245 m and has distinctive responses of gamma-ray, compensating density and neutron well-logging, and so on. In this study, according to the diversities   of   minerals   and   chemical   components   and   well-logging   responses,   eclogites   are   classified from three aspects of origin, content of oxygen, and sub-mineral. We studied the logging identification method for eclogite sub-classes based on multi-element statistics and reconstructed 11 kinds of eclogite. As   a   result,   eclogites   can   be   divided   into   6   types   using   well   logs.   In   the   light  of   this   recognition,   the eclogite in the main hole is divided into 20 sections, and the distribution characters of all sub-classes of eclogite are analyzed, which will provide important data for geological research of CCSD.
